What authority do special agents have concerning the arrest of aliens for removal?

Special agents are granted specific authority regarding the arrest of aliens for removal as part of their law enforcement responsibilities. This authority encompasses the ability to arrest aliens without the necessity of a warrant, based on the circumstances that justify the enforcement of immigration laws. The core duty for these agents is to ensure compliance with immigration laws, which means they can take action against individuals who are unlawfully present within the United States.

The correct answer reflects that these agents have the necessary authority to carry out such arrests directly, streamlining the process of enforcing immigration-related statutes. This authority is pivotal in cases where immediate action is warranted to uphold the integrity of immigration laws.

In contrast, other possible answers suggest limitations or conditions that do not accurately represent the scope of special agents' authority in this context. Special agents do not require a crime to have occurred, nor do they need a judge’s approval for such arrests. Their authority allows for proactive measures to enforce immigration laws, which is essential for managing situations involving alien removals effectively.
